Adapting a automotive from a left-hand drive structure to a right-hand drive configuration could sound like a simple affair, with a easy flip of the dashboard orientation being all that’s wanted. Nevertheless, that is removed from the case, and essential parts typically emerge to redefine the style in how conversions are made, leading to a variety of – typically hidden – design modifications coming about within the swap.
Take security, for instance. Compliance to laws as outlined by a testing protocol can typically present up flaws that will have in any other case not been observed with out the facilitated change, and the parameters for a selected car security programme could reveal one thing one other didn’t.
Living proof, the Proton X50 and its five-star ASEAN NCAP score. Redeveloped from the Geely Binyue, the will to fulfill the best normal outlined within the programme noticed the nationwide automaker making essential, but refined modifications involving materials alternative and the repositioning of elements.
These modifications have been highlighted in an article interviewing Zanita Zainuddin, Proton’s head of Security and Clever Drive. It was her group on the automaker that was tasked with redeveloping the Binyue into the X50 from a safety-related perspective.
Some of the essential modifications concerned remodeling a facet of the physique of the X50. In preliminary crash testing throughout growth, the entrance floorboard typically skilled tearing throughout a frontal collision, which is unacceptable by ASEAN NCAP requirements, because the certification is extraordinarily strict on tears affecting the world across the ft.
To beat this, engineers needed to reinforce these areas with ultra-high-strength metal, successfully shifting the power of influence to different areas that don’t current any menace to occupant security. Total, 40% of the physique, together with the entrance, aspect and again, was made utilizing a mix of high-strength metal variants.
One other technical revision was with the motive force’s footrest, which is situated subsequent to the brake pedal. With the engine all the time oriented below the hood in the direction of the proper aspect of the automobile, whatever the driving aspect, the automaker stated that within the occasion of a collision, the motive force of a right-hand-drive X50 can be extra weak to foot harm as in comparison with the motive force of a left-hand drive Binyue.
The corporate stated that with a view to safeguard the motive force’s resting foot from such hurt, the footrest for the X50 was modified to make sure that the foot stays on the footrest, with restricted slippage.
The nationwide carmaker additionally identified that whereas totally different programmes all comply with a common guideline by way of parameters, some have a barely totally different standards in score a sure facet inside the evaluation. For Geely, its vehicles have been largely made to adjust to the standards set forth by the C-NCAP programme for the home market, which in some areas significantly varies from these set by the ASEAN NCAP.
An instance is with the curtain airbags. The ASEAN NCAP protocol emphasises that the static deployment of curtain airbags covers a spread of physique sorts for the totally different folks which may be driving, one thing that isn’t current within the C-NCAP protocol.
As such, the curtain airbags for the X50 needed to be adjusted to supply further cushioning to the top space throughout influence, primarily in aspect collisions. Since this significantly improves occupants’ security, the design change was out ahead by Proton to the Geely design group for consideration as a staple characteristic in future fashions.
One other studying curve for Geely is within the space of Little one Occupant Safety (COP) security. Apparently, C-NCAP doesn’t at the moment assess the protection of child seats for baby occupants however will probably introduce this evaluation in 2021. This offered Geely with a chance to work along with Proton.
One of many modifications made on this space included lengthening the hook on the Isofix interface, making it simpler to suit a toddler security seat. Additionally, the anchor’s angle was readjusted to supply a safer placement of the seat.
Except for the safety-related revisions, the automaker additionally identified that the driving help options from the Binyue have been carried over aside from the Velocity Restrict Info Perform (SLIF), a characteristic that recognises Chinese language highway indicators and informs the motive force of the present highway’s velocity restrict.
It was defined that if left on, the system might doubtlessly present incorrect info to the X50’s management unit because of language, character and signage variations, and so it was determined that the operate be put apart till it may be tailored to be used in future fashions.
Zanita stated Geely and Proton have each benefited from every model being subjected to totally different security approval and market requirements, with greatest practices gathered and shared throughout the board, nowhere greater than within the area of security.
“Proton has all the time emphasised security as one among its distinctive promoting factors unbiased to any nation or platform. It isn’t shocking then that we proceed to problem ourselves, in order that this DNA is inherent all through our vary of fashions, be it our locally-produced automotive or the present joint growth with our companion Geely,” she stated.
